This means that one strand's sugar-phosphate chain runs in ... Crick were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used ...

During cell division the two strands separate and on each strand a new "other half" is built, just like the one before. This way DNA can reproduce itself without changing its structure -- except ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... The double helix unwinds, and each strand serves as a ...

The double helix structure of DNA is so famous it serves as a sort ... each other like normal (adenine to thymine on the opposite strand, cytosine to guanine) cytosines on the same strand hook ...

In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be "opened" so that specific genes are expressed. Various ...

In the double helix structure of DNA, thymine forms a base pair with adenine ... DNA polymerase enzymes use the existing DNA strand as a template and add the complementary nucleotides, including ...

RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen ... Peptide bonds form between the adjacent amino acids to finalise the structure.
